water pump pully touching harmonic balancer!!! help

[Anonymous]

Ok, i've searched for some information and haven't found anything on it so i thought it was time to start a conversation. I have a 65' econoline previously changed into a 200c.i. from the original 170c.i.... I read infomation that said 200's need a harmonic balancer so i purchased a new one and put it on. I was just installing the water pump pully and fan. Now I find my water pump pully and harmonic balancer are touching. The water pump pully has CODE 8509A stamped on it. Could anyone tell me what i can do to help my situation. Are there differant water pump pullies that are used?

thanks

The early and later pulleys and dampers are different diameters. Some pics of the differences on the above page.

Thanks for the information rick, thats a great page. So now i know what i've got and have a queastion as to what i should do. I have a large diameter double groove pulley and a "short" water pump. Is there a smaller diameter fan pulley that will work with this pump, line up with the big balancer, and not touch each other...thanks again guys

I don't know how much room you have in front of the fan in an econoline. If there is room, it would be time and cost effective to pick up a new late water pump, and get a two or three groove late pulley from the junkyard.

I've never seen one in person, but people have said there are early short pump double groove pulleys that fit with a late damper.
Hens teeth, if they actually exist.

Some options if there is no room would be having a custom pulley turned. This is an expensive option for people that don't have machinist relatives. I had grand ambitions of having a few dozen turned by some starving machinists in the area, but the economy took a bit of an upswing in that field last year and nobody would do a run for a reasonable price.

Mike at FSPP sells (or sold) a double groove small damper.

Using a larger late damper and pulley does have the added benefit of turning the water pump a bit faster.
